[Kobe V²]

Hellow

i have 3 type's of zoa's Radioactive dragon eye, watermelon and god of war.
The dragon eye only opens in the morning ( have them for 6months).
The watermelon has been normal for 4 months in my tank and now it only opens in the morning.
God of war is like half open.
what could be the issue??
these are my parameters from last week.

Are they getting too much light? Also Is there any other corals surrounding them? What are your parameters?

There is goniopora next to it and candy cane and duncans. they do fine and parameters are in my first message.
kh is little low but it swings a lot.

Bring your KH up. Once you adjust your KH you'll see changes in a few days or weeks depending on what condition they are in.
